Getting back into caravanning again after a few years of no van :)

Get everything set for a weekend trip on Friday.

I just checked my nose (tongue) weight with some bathroom scales and I'm happy with it. But I have been reading that the ground needs to be level.

Its on my driveway, a concrete drive, which when looking at it appears level, I can't say I can notice any incline at all. Is this sufficient to get an accurate enough reading of nose weight?

Basically - how level does level ground need to be?

  • Close enough is good enough. Here's a gross simplification i.imgur.com/3PQFK7Y.mp4 So if you're feeling anything weird while driving, stop and fix it immediately.

If you want to eliminate the angle of ground that visually looks flat, measure the weight then turn the whole lot around and measure the weight again. The mean average fo these two readings should give you a fairly accurate idea of the true, level nose weight.

  • Would you clarify please if you mean a 180 degree turn or a 90 degree turn.

    I'd assume he means 180 - so that, for example, if there is a 1:100 downward slope to start with, it'd be offset by a 1:100 upward slope the second time

  • Yes, a full 180 degree turn so that the van is facing the complete opposite direction, thus negating the action of any downward or upward slope. Commented Sep 29, 2016 at 9:00

    I like those self-correcting solutions, very elegant

That's close enough! Especially if you're not pushing the limits.

Tongue weight influences the stability of the rig (too much and the front wheels may tend to lift, too little – especially with a heavy load – and the "tail starts to wag the dog") and the load on the towing vehicle's suspension. You've got some latitude there, probably more than the difference that a hard to see slope in your driveway would amount to.
